This is actually a bug in supermin.  However I think it is fixed in
recent supermin.

Have a look at the patt_of_cpu function here:

https://github.com/libguestfs/supermin/blob/master/src/kernel.ml#L26

This was added by Hilko's patch:

https://github.com/libguestfs/supermin/commit/e8dd485a1737da365bc6af4afb5945817219393e

and I suspect you will need to include this patch in your version of
supermin.  You'll have to also look at the contents of /boot.

Note also that you don't need to install the supermin package in order
to use it, if you follow the instructions here:
